Fatigue life prediction of a radial cylindrical roller bearing subjected to a combined load using fem

Abstract

The article presents the results of studies on the impact of a combined load of a radial cylindrical roller bearing for its predicted fatigue life. The distributions of maximum equivalent subsurface stresses and their depths, necessary during calculations of fatigue life, were determined using the finite element method, using the basic package of the ANSYS program. The calculations took into account the geometrical parameters of the bearing, including radial clearance and the shape of the rolling elements generators. The calculation results showed that the axial load of the radial cylindrical roller bearing and the tilt of the rollers associated with its operation reduces fatigue life. The obtained results were compared with the results of calculations according to the SKF catalogue method, obtaining satisfactory compliance.
